Hello, @polyfractal  
$oES = new ElasticSearchApiManager();  
$sEsIndexToBeFlushed = array(  
'index' =\> 'index\_name'  
);  
$flushed = $oES-\>oClient-\>indices()-\>flush($sEsIndexToBeFlushed);

It returns :

{"\_shards": {"total": 10,"successful": 5,"failed": 0}}

But it doesn't work.  
Does flush method works or not?

Thanks in advance

Hi @rabeetwaqar, sorry for missing this!

The flush method does work, to the best of my knowledge. Why do you think it is not working?

BTW, I tend to keep an eye on the repo more than the forums...so if you need help in the future that's a better way to grab my attention.

Hello,  
Because the data is not getting flushed , it remains the same as it is.

Yeah sure , will follow you up there 😄

Thanks

I think you may be having a different problem. Flushing in Elasticsearch just means the non-committed Lucene segments are committed (fsync'd) to disk. It basically tells Lucene to make buffered in-memory data structures durable on disk. It doesn't affect "searchability" or how data is indexed at all.

Yeah i think i'm having some other issues.  
Btw i'm now using deleteByQuery with params :

'query': {  
'match\_all': {}  
}

It deletes all the data 😉 i know its not a good way to do this but will see flush method when i will have extra pair of time. 😉

Thanks

If you just want to delete all your data in an index, there is a Delete Index api which will be much faster / safer:

```php
$client->indices()->delete([
  'index' => 'my_index'
]);

```
